Is your feature request related to a problem? Please describe.

The real-time audio transcription using Amazon Transcribe was added in https://github.com/aws-samples/aws-sdk-js-notes-app/pull/7 It's not a problem, but it would be good to have an example of converting text to speech using Amazon Polly.

Getting Started Developer Guide for AWS SDK for JavaScript (v3) contains an example of using Amazon Polly in the frontend.

Describe the solution you'd like

Ability to read notes using text to speech with Amazon Polly.
